-Subject: [PATCH 5.12 regression fix] Bluetooth: btusb: Some Qualcomm Bluetooth
- adapters stop working
-
-This issue starts from linux-5.10-rc1, I reproduced this issue on my
-Dell Inspiron 7447 with BT adapter 0cf3:e005, the kernel will print
-out: "Bluetooth: hci0: don't support firmware rome 0x31010000", and
-someone else also reported the similar issue to bugzilla #211571.
-
-I found this is a regression introduced by 'commit b40f58b97386
-("Bluetooth: btusb: Add Qualcomm Bluetooth SoC WCN6855 support"), the
-patch assumed that if high ROM version is not zero, it is an adapter
-on WCN6855, but many old adapters don't need to load rampatch or nvm,
-and they have non-zero high ROM version.
-
-To fix it, let the driver match the rom_version in the
-qca_devices_table first, if there is no entry matched, check the
-high ROM version, if it is not zero, we assume this adapter is ready
-to work and no need to load rampatch and nvm like previously.

+

+Flush; invalidate; change registers; invalidate; flush.

+Will this finally work on every device? Or will Baytrail complain again?

+On the positive side, we immediately see the benefit of having hsw-gt1 in
